ROPE-CLAMP.

Application led February 25, 1921.

To all LU/10m t may concern:

Be it known that I, Josnrn OPPMAN, a citizen of the United States, residing in Connellsville, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Rope-Clamps, of which the following is a specification.

This invention relates to rope clamps, and the primary 'object of the invention is di rected to a novel and improved casing for receiving a portion of a rope or cable whereby the same may be securely held in clamping position and readily released therefrom when desired.

Another1 object of the invention is directed to a rope clamp wherein the inner portion of the rope is clamped between the casing and a rotatable member carried thereby, including provision for releasing the rope without removing the same from the rotating element or casing. Y

Another object of the invention is directed to a novel and improved rope or cable clamp having doubled, manuallv actuated rotatable members carried and supported within a casing for cooperative engagement with each other and with a portion of a rope whereby the same may be clamped between the said casing and the rotatablemembers.

A still further object of the invention relates to a rope clamp of the type above set forth including an open casing having corrugations on its inner periphery ior engage# ing a portion of a rope between the said corrugations and a manually, grooved rotatable element eccentrically mounted within the said casing whereby the rope may be clamped and released without removing the same.

`With these objects in view and others which will be suggested` and manifest as the purpose and nature of my invention are revealed in the following specification and drawings,

Figure 1 is a view showing the interior of the clamp and the rope or cable in clamping position.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1 looking in the direction of the arrows.

gig. 3 is a modified form of the invention, an

Fig. 4 is a sectional view taken on the line 4 4 of Fig. 3.

Referring now to the specification where like numerals designate corresponding parts throughout the' drawings. 5 designates in its Specification of Letters Patent.

entirety a circular casing having an open front face 6, the wall of said casing being provided with an enlarged recess 7 stamped out from said wall and terminating in an upwardly `extending curved hook 8 from which the clamp and its rope or cable may be suspended. The inner flange 9 of the casing is preferably of a width slightly larger than the diameter of the rope 10 to be clamped, said rope extending through a recess 11 in the flange portion of the casing and trained about a pair of manually actuated rotatable elements 12, 13 as clearly shown in Fig. 1.

The respective rotatable elements 12, 13 are eccentrically mounted as at 14, 15 to the casing and just above the opening 11, above referred to, whereby the cable or rope 10 may be clamped or locked between the flange portion 9 and the said rotatable elements. For this purpose each of the rotatable elements are preferably grooved as shown at 16, 17 to receive the bight portion of the rope or cable and are also provided with blunted .teeth 18 for clamping the said rope.

Referring to Fig. 1 it will be seen that the rotatable elements are also formed with segmental teeth 20 which are adapted to mesh with each other when the rotatable element 13 is turned by the thumb nut 21 on the outer face of the wall 6 as shown in dotted lines in the said figure.

From the above construction, it will be readily seen that as the rope or cable is first loosely trained about the rotatable element, the said rope may be clamped by simply turning the thumb nut 21 whereby the segmental teeth 20 will bring the blunted teeth 18 into clamping engagement with the rope lying flush with the flange portion of the casing. .Tt will be obvious that by reversing the thumb nut 21 that the rope may be re leased from clamping engagement and moved )is desired.

Referring now to the form oi the inveution shown in Fig. 3, it will be seen that l. have shown but one rotatable element 25 which is eccentrically pivoted as at 26 and also provided with a thumb nut 27 for rotating the same. It will be noted in this instance that the casing is substantially simi lar to the form shown in Fig. 1 except that I have shown grooved corrugations 28 eX- tending for a short distance on the flange 29 above and upwardly from the recess 30 of @eine mamme .element this case is somewhat larger than the rotatable element shown in the form of Fig. l, but 1s also grooved on its outer 4periphery 8l to rescribed is not thought, to be necessary in View of thev Clear drawing forming a part of this invention, as described above in detail.

In the aeconipanying1 drawings, l. have shown and described my improved clamping` means which in practice has been found. to be highly satisfactory iii-obtaining the desired results. lt will be obvious however that other embodiments inay be adopted and that various changes inthe details of construction Inay be resorted to by those skilled in the art Without departing from the spirit and` scope of the invention. lt is Vfurtherinere understood that the invention is not necessarily liniited or re; icted to the precise elements shown and the modifications described except in sof far as such lin'iitations are specilied in the subject matter beingclaimed.

Having shown' and described iny -inven tion what l now clairn as new and desire to secure by Letters Patent of the Unit-ed States is: pl. A rope clamp comprising, an annular` casing,v rota-tableV means pivoted Within the casing eccent-rically with respect to the peripheral Wall then'eof,` said' Wall' beingl cut away to pern'nt a. rope or cable to be trained about saidA rotatable means, and engaged thereby in differentclampingw positions with Y the neri Jheral Wall' of the casino' adiacent n l1 J the cutaway portion thereof.

A rope clamp comprising support ii'late'havino an annular flane'c one side e l C) C thereof, a rotatable element eccentrically pivoted to the inner side of said plate, said flange'being` cut away to peinit a rope or cable to be trained about said rotatable elenient and engaged thereby between said ele-- :ment and the annular Vilange in different A further and more extended description of the clamping device above declamping positions adjacent the cutaway portion.

3. In a rope clamp comprising a plate having an annular flange at one side thereof, a pair of eccentrically pivoted elements havA ing cooperating teeth thereon rotatably earried by the inner side of the pla-te, said eleinents being grooved and provided With blunted teeth on their periphery for receiving and engaging a rope in different clainping position with said flange, and a supporting hook stamped from Ythe body of the plate.

41;- A rope clamp comprising a plate having an annular flange integral therewith, a pair of eccentrieally pivoted elements having` cooperating` teeth thereon rotatably mounted to the inner side of saidV plate, said flange 'being cut away to permit a rope toY `adjacent the cutaway portion, corrugations formed on said: flange in proximity to the cutaway portion and external iucans for aotuating said element to clamp and release the rope from engagement with theV eorrngations.

G. ln rope elanio c m1prisino` a supp able plate havingaan annular flange, a tat'able greeted lenient, eccentrieally pivot-- ed' on the inner ice-of said plate, said lil c beingzcut away toperniit a rope to be trat red about" about and; engaged by said rotatable element in different clamping positions with the flange ad :ent the cutaway portion, corrugations formed on said flange in proximity tothe cut array portion, external n' the outer face of the plate actua rotatable element to the left. or clamp and release therope frein en With the corrugatlons.

ln testimony whereof l allii my sign hereto.
